Abstract (en)

A water tank (100, 200) for a fuel cell includes a chamber structure (110, 210) including: a body (111, 211) having an inner space defined therein to receive water therein; and an inner partitioning wall (112, 212) extending from a bottom of the body to a predefined vertical level to divide the inner space into a condensed water receiving space and a to-be-supplied water receiving space; an off gas receiving pipe (129, 220) including: a first pipe having one end disposed within the condensed water receiving space and a second end disposed outside the inner space; and a second pipe disposed outside the inner space and connected to the first pipe and receiving exhausted gas containing water vapor; a water and air separator (130, 230) coupled to the second end of the first pipe; a gas blocking wall (150, 250) extending downwardly from a portion of the cover of the body between the inner partitioning wall and the off gas receiving pipe into the water contained in the condensed water receiving space; and an evaporator connection pipe (160, 260) coupled to the body to penetrate a portion of the cover of the body defining the to-be-supplied water receiving space, wherein the evaporator connection pipe supplies water received in the to-be-supplied water receiving space to an evaporator.
